Ee 1t known that i. Lewis (l. Means, a .C 1 f l citizen or ne United States, and a resin dent of the borough of Brooklyn, in

of New York, county of Kings, and vStato o' New York, have invented certain new and useful llnproven'lents in Tabnlating vlvechaaiism on Type-'lvlhsiting Machines, of

which the following is 'a specification.

The present invention relates to typewrit machines and particulalllfY to tabulating .mechanism associated theren' L The n=ain object and feature ot the invention is tcprovide a so called decimal tabnlating mecha. nisln of such construction that its parte ted with the parte of the ordinary" tabnlating ni ehanisin of existing machines, and therefore can be readily, applied to' typewriting machines already on the market. l'

ln the accompanving drawings, the .invention is disclosed in a concrete and pre ferred form, in whehl f Figure. l is a vertical., longitudinal seotional View of the Well known. Royal Ina chine, with parts omitted for the salie clearness, showing the attachment in place. Fig. 2 is a fragmentary view in. front elevation, and with parts broken away, of a bearing attached to the lower front bar oi the frame of the machine for supporting the forwardly extending actuating members of the tabulating attachment, and for securing' an indicating scale in position onsaid bar.

cated at and 9 is a transversely movable carriage, supporting a platenV 20. Suitable carriage escapeincnt ine-ans are" provided here taking the forni of a rack l0 pivotally supported at '101 on the carriage and normally held in engagement with escapement pinion l2 by means of spring 11. Mounted on the carriage is also a. tabnlating; [par lll having one 01;' more adjustable stop, members l5. 14 Yis in the form Off-.t rack, anal stop member l5 .may be adjusted to occup any letter space positiona The ordinary tabniating stop is here in the 'form of a memf ber 16 pivotally supported intermediate its ends on al bracket- 17 and having its end 39 mf :onnected by means of link 40 and arms 40, l

a0 to tabulating key' 18.' .Sring 4:4 normally keeps stop 16 ont of the path of 15.` i3 is a carriage releasing lever pivotally supported on the framework which when tilted lifts rack l0 out of engagement with pinion` l2.-`A l-, extending downward fronti said lever, is adjacent to the lower end la of tabulating stop 16. lt will be understood that when key 18 is depressed upper-end or" 16 moves into the path ofstop member l5 and lower end ofel tilts li); and lifts rack 1G thereby permitting the oarriage to move transversely until l5 and i6 engage. 19 v indicates the usual keys for printing lete5 ters or n bers as will be understood.

2l indi es a plurality or a group of selectively operated tabulating stops consti tnting a means for obtaining decimal tabula.- ti'on. .As here shown these stops are in the i form of levers pivotally supported, independently of each other at a4 point intermediate their ends, onvshaft 22. This shaft is carried by bracket 17 attached to the rear. wall of frame of the machine, said bracket es having an extension 24 which forms an abutment to receive the'tlirnst of carriage `when it strikes one of tbe stops 21. lt will be observed that tbe upper'free ends of y these levers will be in position to dizoct-ly 10o engage a. member l5 on bar l when leverl is rocked into -its path and there are no additional,elements betw and l5, ln order to actu-ate the carriage release mechanism when' any of the stopsl are les in tabulating position, here is provided bail @that lies in front of all the levers' and is mounted en .shaft 22 by Ineansvof ,flanges 41a, said flanges being connected by means of tie rod vlt will be seen that le gna 'when any one levers 21 moves into tabulating position bail r-l1 will he moved for- Ward and will engage stop or abutment'l on tabular stop 11' and will impart a limitinovement thereto insiulicient to bring it into the path rif-1.5, but siillicient to cause 13 to lt racl. 10 out of engagement with pin- Silop l2 is in the form ol' an eccentric washer secured by a sct'screw so that an adjustment may be etlected with relation to ends 23 oi. armsl 21. t will also be noted that spring el is curved out and in to clear plate 41 and allow access to stop 42.

A plate is secured to the i'ear bottom of the frame S by being clamped between the toot pieces Q13 and the Jframe. This plate 25 has slots 27 through which the lower ends ol levers 2,1 pass and are guided. Rods or bars are connected with the lowery ends ci the levers and pass beneath the machine so as to extend beyond the front ot' the frame and are there provided with push buttons or heads 2S). The rods 28 are pressed for` ivardly, and stop arms 23 are held away .troni the tabulating rack by springs 3() connected ybeteren collars 100 on the rods and a plate 31 provided With holes 32 that guide and support the rods. Collar 100 is open at the bottom and is over-size with respect to rod o@ and is secured thereto by means .1U oi set screw 100g. In this w'ay the collar may be renewed from rod 28 without disconnecting the latter. Plate ill is formed at its upper part to seat in the upper central depression 10J. on the lower front bar 33 ot' the frame iii front of the bank of keys and secured to the rear wall of the trent bar by screws Bel. The top of plate 'll carries a scale 35, preferably held between the top ot' the plate and bar 33, the top of the plate beineslotted and the bar iorn'iing a bolster for the scale. rl`lie scale on a strip 36 of `iitable material supj'iorted by a base strip 37 and covered by a strip of transparent material 38. rlhe strip 3G and its adjuncts 37 and 38 are held in the upper part of Iplate Z55 by the ends or' the top ofthe plate .being bent downwardly and then. bent under backing' Si?? as al, 41', a. portion ot' 3l also 'being' tent -toiwvardly and downwardly at l?, 2 yand 3.

Plate carries a stop 102 to limit the rearward movement ol" the loiver end of levers 21, and a second stop 1015 to limit the torward n )vement of said levers. Both of these are in the nature of buffers, and

the

'ear stop fs adjustable as shown in Fig.

l 8 by means ot slots 104e and set screws 105.

incassa receive rivets or screws 113 that extend into bracket 17 (Fig. 1).
